[Age-related variation of adductor weight in the japanese scallop Mizuhopecten yessoensis (Jay) depending on cultivation technique].
Age-related variation in the absolute and relative adductor weight has been studied for 8 years in six samples of Japanese scallops Mizuhopecten yessoensis (Jay) of different generations from a shellfish farm in Alekseev Bight, Sea of Japan. The test character has proved to vary widely within the samples, with variation in shell size being relatively low. It has been shown that the dependence of adductor weight on the age of the scallop is not absolute: even-aged samples from different generations may differ significantly in this character. It is assumed that this effect is due to the influence of environmental factors on the development of scallops at early stages, which is especially strong under conditions of dense spat planting in the course of cultivation.
